Found this and needed to remember it, so excuse the note to self ;-)

Formulas for calculating memory
The following formulas give an approximation of how you need to set the arguments. These
formulas are not exact and may need to be adjusted according to your processing needs.

MEM_INT=MEM_MAX
NEWSIZE=MAXNEWSIZE=1/3 OF MEM_MAX
PERMSIZE=MAXPERMSIZE
PERMSIZE < MEM_INT
MEM_MAX MAXPERMSIZE <= 3/4 physical memory

MEM_MAX MAXPERMSIZE <= 4GB RAM
